DRIVE CONTROLLER, TRANSPORT DEVICE, IMAGE FORMATION DEVICE, AND DRIVE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a drive controller capable of highly precisely detecting a malfunction generated at drive means or a load.SOLUTION: The drive controller includes: control means for generating a voltage indication signal from a target signal and controlling drive means; malfunction detection means for acquiring the voltage indication signal within a detection period by M(M≥2) counts and detecting generation of a malfunction when the number of counts in which the voltage indication signal has been out of a predetermined range in the detection period is not less than N(1≤N
